Master Lock Co 5T Laminated Steel Padlock 2 Pack

Product Description

The MASTER LOCK CO 5T is a laminated steel padlock sold in a 2-pack with a keyed-alike configuration, making it a practical choice for securing multiple access points with a single key. Each lock features a 1-inch hardened boron alloy shackle with a 3/8-inch diameter, engineered for superior cut resistance in demanding environments. A 4-pin cylinder helps prevent picking, while dual locking levers add extra pry resistance. Designed for use by facilities managers, contractors, and trade professionals who need consistent, reliable keyed security across multiple locks in a single purchase.

The 5T padlock is suited for residential and light commercial applications including gate latches, storage units, tool cribs, equipment enclosures, and job-site lockout/tagout scenarios. The keyed-alike feature simplifies access management when multiple locks are deployed at the same location. The laminated steel body construction provides durability in both indoor and outdoor settings where a compact 2-inch body size is required.

Installation Notes

Installation requires no tools beyond threading the shackle through the hasp or latch hardware. Before deploying in a lockout/tagout application, verify compliance with OSHA 29 CFR 1910.147 energy control procedures. Inspect shackle clearance on the hasp to confirm the 3/8-inch diameter fits the receiving slot before closing.
